P07EF Transmission Range Multi-Function Select Circuit Low
Multi-function select circuit reads stuck low — short to ground or pegged at minimum. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
